Overview
Causes
Clinical Presentation
Diagnosis
In terms of determining the etiology a careful history is most instrumental. If the patient has CAD (coronary artery disease) risk factors, known CAD, or angina then a workup for CAD should be undertaken with coronary angiography. A viral prodrome such as viral URI or viral gastroenteritis may make viral myocarditis as a more likely cause. If the patient was exposed to chemotherapy such as anthracyclines then this would be the likely cause. Patients at risk for HIV should undergo testing as HIV can cause a dilated cardiomyopathy. Peripartum cardiomyopathy most often occurs 1 month prior to expected delivery or 5 months after delivery, so recent childbirth is important information. Often by 8 months gestational age pregnancy is physically apparent but it is important to rule out pregnancy in women of childbearing age with dilated cardiomyopathy. Screening questions regarding cocaine or alcohol abuse or other toxin exposure (such as cobalt) should be addressed.
